TEMPORARY BINDER.

Specification of Letters Patent.

Patented Oct. 12, 1915.

Application filed November 1, 1910. Serial No. 590,103.

sented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in temporary, or loose leaf binders, and has been designed particularly for a binder for sheet music, photographs and the like, though it may be used for any other purpose for which it is appropriate.

It is one object of the present invention to produce a binder provided with an improved holding or binding means, and an improved carrier cooperating with the holding means, whereby the carrier may be inserted or removed from the binder without manipulating the holding or binding parts thereof, and in which the carrier when inserted may have a free turning movement.

It is a further object of the invention to provide a guiding means for the carriers, so that they may be turned more readily or quickly in the binder, without displacement. These objects are generally efiected by providing in a binder, holding or binding members mounted in a suitable support, which are substantially arch-shaped and smooth so as to present a free path to the.

turning movement of a carrier, and a notched carrier of such flexibility that it may be sufficiently bent to bring it into engagement with the holding members, and so constructed as to have a free turning en gagement with the holding members, and so that a carrier may be inserted or removed without disturbing or disarranging any other carrier or carriers already in the binder.v

For a full understanding of the invention,

a detailed description of the same will now be given in connection with the accompanying drawings, in which Figure 1 1s a perspective view showing the binder in open position with a number of carriers in position; Fig. 2 is a view similar to Fig. 1, showing thebinder in closed position; Fig. 3 is a cross section taken .on the line 33, Fig. 1'; Fig. 4 shows a form of carrier to which a sheet may be attached,

provided with the preferred form of entering and turning notches, and Fig. 5 is a view of a carrier in the form of a sheet or leaf.

In accordance with the invention, there are provided a plurality of holding-or binding members, the form and construction of which may be widely varied. These members are preferably generally of continuous arch shape, formed to present to the carriers a smooth engaging surface to permit the carriers'to be readily turned over these holding members. In the particular construction illustrated, there are two of these holding members each formed of suitable material, such as wire, bent to arch or loop shape and indicated in the drawing by the numeral 1. These wire loops are secured or mounted in a suitable support. In the particular construction illustrated, the binder is shown as having a pair of covers 2 between which is located what mav be termed 'a back piece 3, which' may be readily formed by the covers and a stiffening piece or member '3, the back piece so formed acting as a support for the holding loops 1.- The loops 1 are supported inthis back piece in any suitable manner. As shown, the loops 1 are located near the opposite ends of the back piece 3, and have their ends bent angularly to the body of the loop, forming projections or feet, as shown in dotted lines in Fig. 1, these ends or feet lying parallel with the back piece. These bent ends are held in position by a reinforcing piece or strip 4 which is secured over them and holds them between it and theback piece 3. These loops thus formed and secured provide a very simple and efficient holding device for the carriers which are to be held byvthem.

To cooperate with the holding members, as described, there are provided loose car-' riers of improved design, these carriers bearing or carrying the matter which it is desired to bind in the binder. The particular form and construction of these carriers may be varied, but they will be so formed 'that they may be inserted in and removed from the loops without manipulating the may be somewhat varied. They will be however-of such character that the carriers may be brought into engagement with the loops, and at the same time have a free turning movement on the loops. In the preferred construction, two sets of notches are provided, one of these sets of notches providing for the entrance engagement with the loops, and the other of these sets providing for free turning engagement with the loops. While one set of notches might be employed if the notches were of sufficient dimensions to permit the carriers to be readily turned, by the use of two sets a somewhat stronger construction is obtained and one which may be more easily and readily manipulated. tion illustrated, the carrier S is provided with notches 6, 7, extending inwardly from the top and bottom edges of the carrier and near one end thereof, these notches being oppositely disposed and with their edges running parallel with the length of the carrier. These notches 6,-7 are the entering notches, and are of a width but slightly greater than the diameter of the wire loop,

'so that the liability of the notched portions of two carriers becoming entangled will be avoided, which would be very likely to occur, if the notches were of considerable width. Furthermore, with such narrow notches the carriers are stronger at the corners than if wide notches were employed, and less liable to break at those points. The second set of notches provided in each carrier to permit a free turning movement are marked 8, 9, and join with the entering notches 6, 7, preferably at the inner ends thereof, the walls of these notches being parallel with the Width of the carrier, and of suflicient width and depth to allow free turning of the carriers about the loops.

As shown in Fig. 5, the carriers S may be in the form of sheets or leaves of sufliciently heavy material to withstand frequent handling and prevent tearing at the corners, and of sufiici'ent flexibility to permit them to be bent to bring them in engagementwith the holding members. With such carriers, the matter to be bound may be printed directly on the carriers, or printed on other sheets or surfaces which may be pasted or otherwise suitably secured thereon. In many instances, as where a sheet is of light material, as a sheet of music, which would be liable to injury if much used, a carrier such as shown in Fig. 4 is preferably employed to which the sheet is attached. In

the preferred construction, this carrier is in the form of a strip 10, of material not liable to injury from frequent use, but of suflicient flexibility to be bent into engagement with the holding loops. This strip is provided with entering and turning notches similar to those already described, and with suitable In the particular construc-v attaching means, such as a gummed edge for securing the sheet thereto. The provision ofthis form of carrier provided with sheet-attaching means is further desirable and advantageous in that a number of these may be providedwith each binder, to which sheets may be attached by the user as desired. It will thus be seen that a very simple and eflicient binder is provided, in which the carriers may be readily inserted andremoved, and in which they may be readily turned. To render the manipulation of the carriers in the binder more easy'and certain, in the best constructions there will be'provided a means for holding the inner ends of the. turning notches in engagement with the loops during the starting movement of turning the carriers, so that said ends of the turning notches will follow and keep in engagement with the loops and prevent the carriers from binding on the loops. This binding would be apt to occur if there were nothing to prevent the sheet being pushed inwardly, so that the holding members come in contact with the outer ends of the turning notches,a condition which might very often arise when a user started to turn the sheet. These means furthermore will act to spread the carriers apart and keep the turning notches in engagement with the holding members when the binder is open so as to prevent the sheets from becoming displaced. These means may be somewhat varied, but will include a guide 11 which guide may be readily and cheaply formed of a loop of wire secured on the support as are the holding loops 1 before referred to, and

between the same. The legs 12, 13 of this guide loop engage with the edges of the carriers and act to hold them, so that the inner ends ofthe turning notches are held in engagement with the loops 1 as indicated in Fig. 1. The engagement of the guide with the edges of the carriers also tends to hold the carriers in positionwhen they are in the 'binder and prevents them from being displaced. The carriers are held almost as sohdlyas if permanently bound. In order not to impede the turning of a carrier, this guide is of not greater, and preferably of somewhat less, height, than the holding loops, as illustrated.

1 It will thus be seen from the foregoing that a very cheap, durable and eflicient looseleaf binder and carrier therefor are pro-. vided by the present invention.

It will be understood that the invention is not to be limited to the precise construction illustrated and described, but that changes and variations may be made in the same without departing from the invention.

What is claimed is u 1. In a temporary binder, the combination with a pair of covers, of a support between the covers, stationary holding members of unbroken arch form mounted" on the support, a flexible carrier provided with oppositely disposed entering notches, and turning notches angularly arranged thereto and permitting a free turning engagement with the holding members.

2. In a temporary binder, the combina-' tion with a pair of covers, of a support between the covers, stationary holding members of unbroken arch form mounted on the support, a flexible carrier provided with oppositely disposed entering notches and turning notches angularly arranged thereto and permitting a free turning .engagement with the holding members, and a curved spreading guide located on the support between the holding members.

3. In a temporary hinder, the combination with a plurality of holding members and a support therefor, of a flexible carrier having oppositely disposed entering notches for engagement with the holding members, and turning notches for permitting the carrier to have a free turning engagement with the holding members.

4. In a temporary binder, the combination with a plurality of holding members and a support therefor, of a flexible strip having oppositely disposed entering notches extending inward from the top and bottom edges of the strip for entering engagement with the holding members, and turning notches of greater dimensions connected to the entering notches at substantially right angles whereby the strip may have a free turning engagement with the holding members. Y I

5. A carrier of flexible material for use in binders having rigid stationary holding members, said carrier having oppositely disposed entering notches extending inward from the top and bottom edges of the carrier for entering engagement with the holding members, and turning notches connected with the entering notches at substantially right angles thereto and of greater dimensions than the entering notches, whereby the carrier may have a free turning engagement with the holding members.

In testimony whereof, I have hereunto set my hand, in the presence of two subscribing witnesses.
